HUB-ATTACHING DEVICE.

- SPECIFICATION forming part of Letters Patent N 0. 684,664, dated October 15, 1901.

Application filed July 16, 1901.

To all whom it may concern.-

Be it known that I, NATHAN S. ANDERSON, a citizen of the United States, residing at Kerens, in the county of Navarro and State of Texas, have invented a certain new and useful Hub-Attaching Device, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to hub-attaching de vices, the object in View being to provide a simple, cheap, and reliable retaining device for holding vehicle-wheel hubs in place upon their axles or spindles, doing away with the usual threaded nut and entirely overcoming the liability of such nut or retaining device working loose.

The primary object of the invention is to do away with screw-threads and at the same time produce a retaining device which is capable of being easily and quickly applied to an axle-spindle and as easily removed whenever it becomes necessary to detach a wheel.

Another object of the invention is to overcome any liability of the retaining device becoming dislodged by accident or in ordinary handling.

With the above and other objects in view, the nature of which will appear more fully as the description proceeds, the invention consists in the novel construction, combination, and arrangement of parts, as hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a longitudinal section through a wheel-hub, showing the same mounted upon a spindle and held in place by means of the hub-attaching device forming the subject-matter of this invention. Fig. 2 is a view in elevation of the hub-attaching device, illustrating the elliptical or flattened shape of the springring. Fig. 3 is a perspective View of the same. Fig. 4. is a detail perspective view of the lower segment of the device, showing the spring-ring thrown downward. Fig. 5 is a plan view of the Wrench or spanner for placing and displacing the spring-ring.

Similar numerals of reference designate corresponding parts in all the figures of the drawings.

For the purpose of illustrating the present invention I have shown in Fig. 1 an axle 1,

Serial No. 68,494. (No model.)

provided with the usual spindle extension 2, 3 designating the inner bearing-sleeve of the hub, the latter being shown at 4:-

In carrying out the present invention the outer end portion of the spindle is formed with an annular groove 5, which has the effect of providing oppositelylocated inner and outer shoulders 6 and 7, respectively, the shoulder 7 forming the inner face of a collar 8 at the extremity of the spindle.

The hub-attaching device or retainer com prises, essentially, a pair of semicylindrical segments 9 and 10, which meet on a line diametrical to the axial center of the spindle 2, the line of meeting being designated at 11. Furthermore, each of the segments is provided at its inner end with an enlarged semicircular flange 12, so that when the two segments are brought together a complete annular flange is formed atthe inner end of the retainer, which flange is adapted to bear against the outer end of the hub l, as shown in Fig. 1. The segments 9 and 10 are of a size adapting them to fit snugly between the shoulders 6 and 7 on the spindle, so as to pre- Vent movement of the retaining device longitudinally of the spindle.

In order to provide for holding the segments upon the spindle and in engagement with the groove 5, said segments are encircled by a spring-ring 13, which is somewhat elliptical in shape, as indicated in Fig. 2. The ring is connected to one of the segments, as 9, by passing the same through a keeperloop 14: on said segment. The other segment 10 is provided at a point diametrically opposite from the loop Ll with a groove or depression 15, forming a seat into which the springring is adapted to snap when forced over the segment 10, the engagement between the ring and segment 10 being indicated by the dotted line 16 in Fig. 2, such dotted line indicating the base of the groove or depression for the reception of the ring. The segments are further properly positioned and held with respect to each other by means of dowel-pins 17 on one of the segments, which enter corresponding sockets in the meeting face of the opposing segment. After placing the wheel upon the spindle the segments 9 and 10 are brought together at opposite sides of the spindie between the shouldersG and 7 until the dowel-pins 17 enter the sockets in the op posing segment. The spring-ring 13 is then sprung, so as to cause it to pass over the outer ends of both of the segments, and said ring is then forced onto the segment until it snaps into the depression 15, being held therein by reason of the resiliency of thering and the tendency for said ring to resume the elliptical form shown in Fig. 2. In order to remove the retaining device, it is only necessary to reverse the operation just described.

In order to facilitate the application and removal of the attaching device, I usually employ a Wrench or spanner 19, provided with oppositely-located arms 20 and 21, the arm 20 being straight or plain, While the other arm 21 is provided with a terminal inbent hook 22, which is adapted to engage either behind or in front of the spring-ring, While the end of the straight arm 20 bears against the outer surface of one of the segments and forms the fulcrum of the wrench or spanner.

From the foregoing description it will be seen that all screw-threads and nuts, as such, are dispensed with and the consequent liability of the nut to work loose. The attaching device herein described is simple in construction, cheap in manufacture, and forms a reliable fastening device for holding the wheel-hub in place. At the same time the retaining or attaching device may be displaced or attached for allowing the wheel to be removed whenever required.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a grooved and shouldered spindle, of a hub-attaching device consisting of a pair of semieylindrical segments adapted to fit the grooved portion of the spindle, one of said segments being provided with a depression, and an elliptical spring-ring adapted to snap into said depression, said ring being loosely connected to the opposing segment.

2. The combination with a grooved and shouldered spindle, of a hub-attaching device comprising a pair of semicylindrical segments having a dowel-pin connection, one of said segments being provided with a depression, and a flattened or elliptical-shaped springring loosely connected to the other segment and adapted to snap into said depression.

In testimony whereof I affix my signature in presence of two witnesses.

NATHAN S. ANDERSON.
